BURNER FOR LAMPS.

Specification of Letters Patent No. 22,230, dated December 7, 1858.

To all whom 'it may concern:

Be it known that I, M. B. Dro'r'r, of the city and county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in the Manner of Regulating Generating FluidGas-Lamps; and I do hereby declare the following to be a full, clear,and exact description of the construction and operation of the same,reference being had to the accompanying drawings, making a part of thisspecification, in which- Figure l, represents a perspective view of thelamp top, and Fig. 2, represents a vertical section through the cap andtube, leaving t-he heater and pin or spur uncut.

My invention consists in so constructing the lamp top of a gasgenerating lamp as that the light of said lamp may be regulated byraising and lowering the heater and pin, while the head of the burnerremains stationary. Or, by raising or lowering the head of the burnerwith the heater and pin, and my invention consists also in the valve onthe pin, and the valve seat in the inside `of the tube or burner, forthe purpose of opening, or closing entirely or partially, the passagethrough which the vapor or gas passes from the wick to the opening oropenings at which the gas-burns.

To enable others skilled in the art to make and use my invention, I willproceed to describe the samewith reference to the drawings.

A is a cap which may be screwed, or otherwise fastened to the 'bowl orreservoir that contains the fluid from which the gas is to be generated.Around an opening in this cap, is firmly fixed a wick tube B, which maygradually enlarge from its base toward its top. A male screw is cut onthe top of this wick tube B, and the burner C, has a female screw cut onits lower inner perimeter, and is attached to said tube by means ofthese screws, so that it may be raised or lowered on the wick tube atpleasure, or when it is desirable to do so, to regulate the light of thelamp. The burner can be run up or down on the wick tube, by the thumband finger applied to the disk portion a of the burner, which has itsedges milled for the purpose. Or, it may be done by a rod or lever D,inserted in the socket c attached to the burner, or made in it. Theopenings e, e, at which the gas is burned are made through the upperportion of the burner C, or burner head.

An opening is made down through the top of the burner head, in whichopening a screw thread is cut; and in this screw is placed the shank E,having' a male screw thread cut on it, so that it may be raised orlowered in the burner, and allow the burner to be stationary-or, withoutraising and lowering the burner. On top of this screw shank E, is theheater F; and below the screw thread a conical shaped valve orprojection -n which tits into or against a similar shaped seat o formedon the inside of the burner. Below the valve or projection n there is aspur or pin G, which is also a part of the heater and shank E; this pinor spur extends down into the wick (represented in red lines) in thewick tube, and spreads it out against the sides of said tube. A hole s,is made through or into the heater or shank, into which the rod or leverD, may be inserted for the purpose of raising or lowering the heaterwithout moving the burner C. The raising of the heater, brings the valveor projection n against the seat 0, and thus the gas or vapor passagemay be regulated without moving the burner. But if on the other hand theregulating should require the moving of the burner, it can be done, butin this case the burner and heater move together, but carry wit-h themthe spur or pin, which owing to its tapering form presses more or lesshard against the wick. So that the lamp top is capable of two importantadjustments one of which can be made without moving the burner, and theother without changing the area of the opening between the valve and itsseat, but raises or lowers the pin or spur in the wick, and this admitsof so regulating the light and the flow of gas, or the stopping of both,as to make the lamp very perfect in its action.

Having thus fully described the nature and object of my invention, andshown how it operates what I claim therein as new, and desire to secureby Letters Patent is l. Regulating the light of a gas lamp by raisingand lowering the heater, and pin connected to it, While the head of theburner twcenlthe top of the Wick, and the openings remains stationary,substantially as deat Whlch the gas s burned, substantially as scribed.described.

2. I also claim in combination with the M. B. DYOTT. 5 heater andburner, the valve or projection n, Witnesses:

on the one, andthe valve seat 0 on the other, CHAS. F. VARWICK, whensaid Valve and Seat, are located be- F. CURTIS.
